From e1f15ccbae40b55a4e2591373ea5f1808cf29855 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Thu, 6 Sep 2012 20:11:16 +0200 Subject: [PATCH] usb: gadget: use usb_string_ids_tab instead multiple usb_string_id() Using usb_string_ids_tab() instead multiple calls of usb_string_id() seems to be handy. It also allows to add string without many checks.
